IMPROVEMENT IN APPARATUS FOR FORMING HEEL-COUNTERS FOR BOOTS AND SHOES.

Specification forming part of Letters Patent No. 195,845, dated October2, 1877; application filed May '26, 1877.

To all whom it may concern Be it known that I, ETIENNE SALOMON, of thecity of Montreal, in the district of Montreal and Province of Quebec,Canada, have invented certain new and useful Improvements in Apparatusfor Forming Heel-Counters 5 and I do hereby declare that the followingis a full, clear, and exact description, suflicient to enable any oneskilled in the art to manufacture the same.

The principal features of my invention are as follows: I give to thedies or punches (which, working in the molds, shape the sides of thecounter) their backward and forward movement by means of arms operatingthrough knee-j oints, and this in contradistinction to the other usualmeans, such as crank-handles, cams, eccentrics, or a rack and pinion. Iuse a friction-clutch arrangement between the main shaft of the machineand the loose driven wheel thereon, so that in case of any unusualresistance or jam of the machine the said driven wheel may rotatewithout transmitting motion to the machine. Damage to the machine isthus in great measure avoided.

I further propose to form the upturn? by the action of rollers operatedby means of eccentrics. I also provide, in addition to the means fordischarging the finished counters from the molds, a device which throwsthe counter from off the punch or die as soon as this latter has issuedfrom the mold.

For full comprehension of my invention reference must be had to theaccompanying drawings, forming part of this specification, in whicFigure 1 is a plan, partly in section, of the machine. Fig. 2 is a planview of the eccentrics, &c. Fig. 3 is a detail section of kneejoints,enlarged. Fig. 4 is a part side elevation and part longitudinal sectionthrough molds. Fig.'5 is a part end view and part transverse section.Fig. 6 is a part plan and part horizontal section through frictionaldriving-gear. Fig. 7 is a side elevation of rollertail of device fordetaching counter from punch.

Similar letters of reference indicate like parts.

A is the frame of the machine, of any desired form and suitablestrength, in it being formed a bearing for the main shaft, to whichmotion is imparted, as shown more particularly in Fig. 5, and as will behereinafter more particularly described. Secured to the top of thisshaft is an arm, 0, having on its end a roller, C, which, moving in acovered cam, D, gives motion to it backward and forward, the guides Drunning either side of the roller A secured by a pin to the upper partof the frame, insuring the accuracy of the movement. D is an upperplate, secured to D by any number of bolts and distancepieces, or in anyusual way.

Between these pieces D D are pivoted, as shown in detail in Fig. 3, theends of the arms E, which actuate the dies, d d being slots formed inthe plates D D 01, a filling-piece of somewhat smaller size, throughwhich passes the pivot-pin e, securing together each pair of arms E E.The other ends of these arms are, as shown in detail in Fig. 4, screwedinto the heads E a cushion of elastic material being, as at E preferablyinterposed between them. F F are the blocks to which the heads E aresecured, preferably by pins f, or in any suitable way.

G G are the dies, pivoted or otherwise adjustably connected to thedie-blocks F, provided with means, such as springs, elastic cushions,&c., for slightly elevating their free ends.

H is the mold, formed either of soft metal or cast in two parts, andhaving its upper part formed so that, when the die has completelyentered therein, the projection G on the top of the die will correspondexactly thereto.

These molds have interposed between them and the castings I in rear ofthem, and which form part of the frame, elastic cushions h, and are heldin mold blocks H which may be tightened up or slackened by means ofplates H operated by set-screws working 'in lugs H cast on the frame,elastic cushions h being arranged as shown.

I I are spring-cases formed on the casting,

in which are contained rods 1', acting, by means of spiral or othersprings, to throw the finished counter out of the mold.

To detach the formed counter from the die as it returns from the 1nold,Ipivot to the side of the die-block F a bent lever-arm, K, which lies ina groove formed in the under side of the die, and is held in place byaspring or corresponding device, K, the short arm K of this lever beingarranged, as the die-block recedes, to come in contact with anyproiectionsformed on the frame, so as to overcome the action of thespring, and bring down the outer end of the lever, thus throwing offfrom the die the formed counter, openings being left in the framethrough which they can drop into proper receptacles.

I will now proceed to describe the means by which I propose to operatethe roller or similar mechanism for giving the upturn.

Upon the main shaft B, I mount a toothed are, L, which interlneshes withtwo pinions, L, placed at opposite points in the line of the center ofthe guides D. (It may be observed that, by preference, I cut at themeeting-point the first tooth of either the are or pinion, so as toallow the con'esponding tooth of the other to pass it, and take a firmbearing on the second in order.) Guard-plates l and I, mounted,respectively, on the axes of the are L and pinions L, hold the pinionsinthe proper place, so that they will be in the exact position requiredwhen the arc begins to operate them.

L L are two pairs of eccentrics, pivoted, respectively, to the pinionsL, revolving on spindles L and giving motion to the eccentricstrapsconnected by rods L to the bar L, which operates the driving-rod M, atits end terminating in a fork, M. Each end of this fork M is, by aspindle, m, connected with the carriage N, to which is secured a rocker,M, pivoted at m thereto, and having formed on it bearings for thespindle of the roller 0, this part of the apparatus acting to raise theroller to the horizontal plane in which it will exercise pressure toform the upturn.

N is a bush, carried between the two sides of the carriage N, throughwhich passes a pin, 91, pressing on the spindle m, (which joins the twoforked ends M,) and having on its outer end a nut, n, which, as thedriving-rod M presses in, comes in contact with the nut N screwed intothe bush N, stopping the upward movement of the roller, and pressing itin a forward direction. The distance between the nuts n and N, which is,of course, capable of adjustment, governs the amount of lift given tothe pressing-roller 0.

The carriage N moves back and forth along the frame on rollers N eitheror all of which may be grooved to run on ridges, or otherwise guided, toinsure their accuracy of motion.

0 O are small angle-pieces formed on the carriage in advance of theroller 0, and serving to bend up the mill-board, or other material ofwhich the counter is made, so as to partly form the upturn, which is tobe finished by the roller.

The roller, having been, as described, raised to the proper height,presses in its forward motion with great force against thepartiallyformed upturn, (the blank having been previously prepared bycreasing or cutting,) leaving it perfect as the roller, by the reverseaction of the machine, recedes.

P l are the troughs or reservoirs (for greater clearness shown only inFig. 4) containing the blanks from which the counters are to be formed.These are fed to the machine by apparatus which I will now proceed todescribe.

Between each pair of dies is placed, as shown in the drawing, a standardQ, to the head of which are pivoted levers Q Q, operated by lifting-rodsq q, connected at the lower ends by any suitable system of cranks orlevers, such as that shown in Fig. 7, with ends M of the driving-bar M.To the free ends of these levers are attached, by pivoted links q, armsQ, having their lower ends curved to corre spond with the outline of theblank, and moving up and down in slotted guides Q, to catch and pressdown in succession the blanks as they come to the mouth of thereservoir. Q Q show rests, which stop the downward motion of the blanksat the point at which they will come under the action of the dies.

The device of which I make use to give motion to the main shaft will nowbe described. It is a .bevel friction-pinion, rotated by any suitablemeans, hand or power, as desired, and acting upon a horizontal wheel, S,mounted loosely upon the shaft B, and having on its lower side a flange,S, which has, as shown at S downwardly-projecting pieces formed upon it,and fitting in the groove of the ring T, which is bolted loosely to theflange S. U is a friction-piece keyed on and rotating the shaft B. W isthe friction-ring surrounding the ring T, and resting upon the uppersurface of the friction-piece U, to which it is secured by any number ofscrew bolts 10. Between these pieces U and W may be interposed a ring ofleather or other like substance, X, and between the beveled surfaces ofT and U a similar ring, X.

From this it will be seen that, so long as the machine is workingsmoothly, the action of the pinion R is transmitted through the wheel Sand intermediate ring T to the friction-piece U, keyed on and rotatingthe shaft B, and thus operating the machine, the degree of hold of therespective parts on each other being regulated by the bolts w,connecting the friction-ring and friction-piece. Should, however, anysudden stoppage of the machine take place, the intermediate ring T,driven as just mentioned, will revolve freely inside the friction-pieceU without imparting any motion to it, and consequently will stop themachine, thus avoiding the breakage of any of the parts.

To obviate any sudden jerk of the parts in starting the machine, Ipropose to fill the spaces between the pieces S in the groove of thering T, with any elastic substance, as shown at Y, the bolts tconnecting the flange S with the ring T, passing through slots 16 in theflange, as shown in Fig. 6, and pressing against the sides of the'piecesS When the machine is started, the bolts t, moving a little in the slotst, and pressing against the pieces S will compress the rubber or elasticsubstance on the other side of them in it is thoroughly tightened up,when the ring T will begin to move, thus gradually and slowly startingthe apparatus.

The nature of my invention, and the operation of the several parts, willbe so clearly understood from the foregoing description and the drawingsthat I need only remark that the stroke of the roller 0 in the cam D isso arranged as to be divided into four partsthe first part operatingone-half the dies, and

pressing them into corresponding molds. The cam then remains for a timestationary, during which period the machinery for that purpose isoperated by the main axle to form the upturn and complete the counters.The cam thenmoves, withdrawing from the molds the dies previouslypressed in, and forcing into the other half of the molds thecorresponding dies. The cam then, in the last part of its stroke,remains'ahnost stationary, while the eccentrics operated by the mainaxle act to bring in front of the first half of the molds the blanksfrom which the counters are to be formed, and at the same time, asbefore mentioned, to finish the upturns of the counters in the secondhalf of themolds, thus at the same time pressing in and withdrawingfromihe molds the dies, finishingthe counters,andbringingfreshblanks infiront of the molds.

Having thus described my invention, I beg to state that I do not confinemyself to the exact mechanism herein described for accomplishing theseveral purposes,

What I claim being as follows:

1. In a machine for making heel-counters, the combination, substantiallyas specified, of the reciprocatingslide for driving the die-block, thedie-block arranged to move transversely to the line of motion of theslide, and the intermediate connecting-link or toggle-bar.
